- y Letters .Patent No. 95,767, dated October 12, 1869.

*weg-' MROVEMENT IN STOP-MOTION POR DRAWINQFRAMES.

*WH-*- The Schedule referred to these Letters Patent and making part ofthe same.

To all whom it may concern Be it known that I, J Aims S. CASEY, ot'Voluntown, in the county of Windham, and State of Connecticut, haveinvented a new and valuable Improvement in Governors and Stop-Motion'forRailway-Heads; and

and all breakage or other accidents to material or machinery, caused bybunches or lank places in the roving, prevented. It is 'a simple andeicient stop-motion, easily applied.

The letter A, of the drawings, represents the topf drawing-roll, theshaft of which is lengthened, and has secured to its end a smallspur-wheel, a.

B and C designate eccentrics revolving about the pins b and c,respectively. These eccentries are toothed tor about three-quarters oftheir circumference, and so weighted vas to automatically present thelank and smooth side of each to the small spur-wheel on the end ofthetop roll.

The axis or pins b and c are fixed in the ends ofthe gelding-jaws d "d,hinged at d d to the forked support The eccentrics B and C .are diawntoward each other by the spiral spring E attached to the jaws d d, bythe screw-bo1ts andnuts e e, and their distance apart regulated by meansof the set-screws f f iu the forked ends of support D.

The support D isadjusted, so that the eccentrics shall gear with'thespur-wheel a', by means oi' its slotted arm D', in connectionr with thesliding standard G, working in its slotted support F, the whole beingarranged so vas to bring the cecentrics B and 0 to any desiredposition..

The support D is provided'with a fork, H, pivoted at h, whose fingers,adjustable in slotted supports by means of the set-screws h' 71', engagewith the pins b and c', xed at suitable points in the faces of theeccentrics Bv and G. y

Fixed in the opposite end of the fork H is a small prismatic rod, c',which engages in a small notch in the rod I.

The upper end of the rod I is'formed into a handle or knob. Its lowerend`is keyed o n the horizontal rod K.

This rod or shaft K turns in its bearings k k", and has a spiral spring,k, coiled around it, onefend of which is fixed to it by the clamp l, theother end being firmly xed to the bearing k.

The end of the -rod K, which extends vbeyond the bearing It', has twonotches or depressions, one extending beyond'r the other in suchamanneras to release the catch of the shipper whenthe rod K is turned bythe action ofthe spiral spring 7c.

The yielding or up-and-down motion ofthe toproll is placed under perfectcommand by meansof the weights m m and coiled springs s s, producing thenecessary tension for properly condensing the roving.

The operation of my invention is'as follows :v

'lhe evener being setto produc'e the required size or number of roving',the eccentiics B and C of my stop-motion are also set, to bring thelankand smooth portions of their circumference within a thirty-second partof an inch of the spur-wheel a on the end of the is ready for operation.

Now, should the roving break-or run down fine from the cards giving out,or other causes, making it impossible for the evener to keep up thenumber of rovtop-roll, which plavs between them, and the stop-motioning, the small spur-wheel a'will drop, and engage with the lowerecceuimicO, whose pin c' will ,engage with the lower tine of the fork H,raising it, and thereby depressing the small catch t out of the notch inthe upper part ofthe vrod I.

The rod I being released, the sha. K, operated by 'the spiral spring It,turns one-quarter` round, thereby operating the belt-shipper to stop themachine.

v In case-bunches run through, or the rolls wind-up,

the small spur-wheel a'is forced to rise, and engage with the uppereccentric B, whose pin b raises the upper tine of the balanced fork H,and the belt-shipper is caused to throw off in the same manner as beforede- It will be perceived that my stop-motion is not liable to much wear,as it is still, except when called. on to perform its duty.

What I claim as my invention, and desire to secure 1. In combinationwith the eccentrics B and C, or their equivalents, the spurwheel af,secured to the extended shaft ofthe top roll A, substantially as shownand described.

2. The eccentrics B and C, partially toothedand weighted, so as topresent their smooth and lank sides automatically to the geared end ofthe top roll, substantially as specied. I

.i 3. In combination with the eccentrics B and C, the fork H,constructed and arranged to operate substantially as specified.

4. The stop-motion herein described, having sliding I standard G,adjustable support D, with hinged and adjustable jaws d d, eccentrics BO, balanced fork H, spur-wheel a', shaft K, and spiral spring It, al1constr ucted and arranged to operate with the belt-shifter,

.substantially as specified.

In testimony that I claim the above, I have hereunto subcribed my name,in the presence of two witnesses. v Witnesses: J S. CASEY.
